PROPERTIES OF POLYETHYLENIMINES:
The linear Polyethylenimines are a semi-crystalline solid at room temperature, while branched Polyethylenimines are a fully amorphous polymer existing as a liquid at all molecular weights.

Linear Polyethylenimines are soluble in hot water, at low pH, in methanol, ethanol, or chloroform.
Polyethylenimines are insoluble in cold water, benzene, ethyl ether, and acetone.

Polyethylenimines have a melting point of around 67 °C.
Both linear and branched Polyethylenimines can be stored at room temperature.
Linear Polyethylenimines are able to form cryogels upon freezing and subsequent thawing of their aqueous solutions.

SYNTHESIS OF POLYETHYLENIMINES:
Branched Polyethylenimines can be synthesized by the ring opening polymerization of aziridine.
Depending on the reaction conditions different degree of branching can be achieved.

Linear Polyethylenimines are available by post-modification of other polymers like poly(2-oxazolines) or N-substituted polyaziridines.
Linear Polyethylenimines were synthesised by the hydrolysis of poly(2-ethyl-2-oxazoline) and sold as jetPEI.
The current generation of in-vivo-jet Polyethylenimines uses bespoke poly(2-ethyl-2-oxazoline) polymers as precursors.

KEY ADVANTAGES OF POLYETHYLENIMINES:
*Superior Performance:
High transfection efficiency with low cytotoxicity compared to other reagents on the market, suitable for use in larger concentrations and in sensitive cells.

*Low cytotoxicity:
Even larger concentrations of Polyethylenimines disrupt cells minimally

*Flexible Workflow:
Easy to optimize and introduce into application protocols.
Scalable for well plates, flasks, and larger capacity bioreactors.
Available in cGMP grade and in both powder and liquid formats.

*Cost-Effective:
Economical compared to similar transfection products in the market.

TRANSFECTION REAGENT OF POLYETHYLENIMINES:
Polyethylenimines were the second polymeric transfection agent discovered, after poly-L-lysine.
Polyethylenimines condense DNA into positively charged particles, which bind to anionic cell surface residues and are brought into the cell via endocytosis.

Once inside the cell, protonation of the amines results in an influx of counter-ions and a lowering of the osmotic potential.
Osmotic swelling results and bursts the vesicle releasing the polymer-DNA complex (polyplex) into the cytoplasm.
If the polyplex unpacks then the DNA is free to diffuse to the nucleus.

Permeabilization of Gram-negative bacteria
Poly(ethylenimine) is also an effective permeabilizer of the outer membrane of Gram-negative bacteria.

*CO2 capture
Both linear and branched Polyethylenimines have been used for CO2 capture, frequently impregnated over porous materials.
First use of Polyethylenimines polymer in CO2 capture was devoted to improve the CO2 removal in space craft applications, impregnated over a polymeric matrix.

After that, the support was changed to MCM-41, an hexagonal mesostructured silica, and large amounts of Polyethylenimines were retained in the so-called "molecular basket".
MCM-41-PEI adsorbent materials led to higher CO2 adsorption capacities than bulk Polyethylenimines or MCM-41 material individually considered.

The authors claim that, in this case, a synergic effect takes place due to the high Polyethylenimines dispersion inside the pore structure of the material.

As a result of this improvement, further works were developed to study more in-depth the behaviour of these materials.
Exhaustive works have been focused on the CO2 adsorption capacity as well as the CO2/O2 and CO2/N2 adsorption selectivity of several MCM-41-PEI materials with Polyethylenimines polymers.
Also, Polyethylenimines impregnation has been tested over different supports such as a glass fiber matrix and monoliths.

However, for an appropriate performance under real conditions in post-combustion capture (mild temperatures between 45-75 °C and the presence of moisture) it is necessary to use thermally and hydrothermally stable silica materials, such as SBA-15, which also presents an hexagonal mesostructure.

Moisture and real-world conditions have also been tested when using Polyethylenimines-impregnated materials to adsorb CO2 from the air.
A detailed comparison among Polyethylenimines and other amino-containing molecules showed an excellent performance of PEI-containing samples with cycles.

Also, only a slight decrease was registered in their CO2 uptake when increasing the temperature from 25 to 100 °C, demonstrating a high contribution of chemisorption to the adsorption capacity of these solids.
For the same reason, the adsorption capacity under diluted CO2 was up to 90% of the value under pure CO2, and also, a high unwanted selectivity towards SO2 was observed.

Lately, many efforts have been made in order to improve the diffusion within the porous structure of the support used.
A better dispersion of Polyethylenimines and a higher CO2 efficiency (CO2/NH molar ratio) were achieved by impregnating a template-occluded PE-MCM-41 material rather than the perfect cylindrical pores of a calcined material, following a previously described route.

The combined use of organosilanes such as aminopropyl-trimethoxysilane, AP, and Polyethylenimines has also been studied.
The first approach used a combination of them to impregnate porous supports, achieving faster CO2-adsorption kinetics and higher stability during reutilization cycles, but no higher efficiencies.

A novel method is the so-called "double-functionalization".
It is based on the impregnation of materials previously functionalized by grafting (covalent bonding of organosilanes).
Amino groups incorporated by both paths have shown synergic effects, achieving high CO2 uptakes up to 235 mg CO2/g (5.34 mmol CO2/g).

CO2 adsorption kinetics were also studied for these materials, showing similar adsorption rates as impregnated solids.
This is an interesting finding, taking into account the smaller pore volume available in double-functionalized materials.

Thus, it can also be concluded that their higher CO2 uptake and efficiency compared to impregnated solids can be ascribed to a synergic effect of the amino groups incorporated by two methods (grafting and impregnation) rather than to a faster adsorption kinetics.

*Low work function modifier for electronics
Polyethylenimines and Polyethylenimines ethoxylated (PEIE) have been shown as effective low-work-function modifiers for organic electronics.
Polyethylenimines could universally reduce the work function of metals, metal oxides, conducting polymers, and graphene, and so on.

Polyethylenimines are very important because low-work-function solution-processed conducting polymer could be produced by the PEI or PEIE modification.
Based on this discovery, Polyethylenimines have been widely used for organic solar cells, organic light-emitting diodes, organic field-effect transistors, perovskite solar cells, perovskite light-emitting diodes, quantum-dot solar cells and light-emitting diodes etc.
